*       Would like to drop countries that have no recognizable parties  *;
*       since I am interested in determining the number of parties.     *;
*       Drop Kiribati, Marshall Islands, Micronesia, Nauru, Palau,      *;
*       Lebanon (at least no votes by party), Kyrgzstan.                *;
*       Since I am interested in competitive elections I drop the       *;
*       elections that occurred in Colombia between 1958 and 1970 due   *;
*       to a constitutional agreement to share power between the        *;
*       conservative and liberal parties.                               *;
*       Also drop the Congolese elections of 1963.  Although there were *;
*       multiple parties permitted, all candidates ran on a single list.*;
*       Thus, there was no actual competition in this election.         *;
